It’s not just things that go bump in the night that give us pause for thought or a reason to be concerned. Most unusual noises in the home can be traced back to one root cause: the heating system.

Regardless of whether you live in the most modern house with state of the art heating and plumbing systems or an ancient building with rusting pipes and radiators, at some time your heating system is likely to give off a variety of bangs, bumps, rattles or hissing noises. But why does it happen and how do you fix the problem?

Most Common Problems

Firstly, no heating or plumbing system is ever entirely silent. Most modern installations are built to be highly-efficient and almost noiseless but power and pressure must still be generated which will, invariably, produce some sound although this is usually unnoticeable unless you are specifically listening for it.

Most of the common problems that lead to unwanted noises from your radiators or heating system are easily recognizable by the specific sounds they make and quite a number, but by no means all, are reasonably easy to fix.

  • Hums and Whines. Humming noises generally indicate a problem with heating elements that are not set correctly for timing and pressure. If the thermostat is functioning properly, the central heating pump may be running too fast and need adjusting. Turning the pressure down might also be required as excessive pressure can damage pipes and cause clanging noises.
  • Tapping and Gurgling. These noises are generally an indication that the heating system needs to be flushed out due to lime scale build-up in the pipes. A non-acidic cleaning agent can be used to cleanse the system but the sort of chemical cleanser you will need depends on the system’s age.
  • Knocking and Creaking. Pipes will naturally expand and contract according to the temperature of the water or steam they carry. Creaking noises are often caused by floorboards being forced out of position due to insufficient room for pipes and some adjustments may have to be made to the positioning of joists and boards to accommodate the piping. Insulation around the pipes can also reduce or eliminate these noises.
  • Not a good sign as gurgling noises usually mean trapped air. Simply bleeding the radiators will often cure the problem but you will probably need a qualified specialist if the noises persist.

Old Age

Old age comes to us all and heating systems are no different. With newer installations, most noises from heating systems can be easily and swiftly eradicated although you may require the services of a plumber or qualified heating specialist. However, as heating systems get on in years, problems from wear and tear will arise and a quick-fix is not always possible.

Persistent or recurrent noises, even after repair, will tell you that your system has seen better days. If you have consulted the professionals and the prognosis isn’t good, it may be time to bid your noisy heating system a warm farewell.
